Description

一次性使用的体液吸收性穿用物品
本申请是申请人“尤妮佳股份有限公司”提交的申请日为2000年11月17日、申请号为00137149.5、发明名称为“一次性使用的体液吸收性穿用物品”的申请的分案申请。
本发明涉及用于处理排泄体液的一次性使用的尿布、生理用卫生巾等体液吸收性穿用物品。
WO93/09736号公报揭示了具有弹性伸缩性片状物的生理用卫生巾。该卫生巾具有形成卫生巾侧缘部的弹性伸缩性第1片状物，和在卫生巾内面侧朝吸液性芯上方可立起的弹性收缩性第2片状物。第1片状物是将覆盖芯的透液性表面片和不透液性里面片在芯侧缘部外侧重叠地接合而形成的，而在片状物的自由缘部，第1弹性部件在该两片间以延长的状态向片状物纵长方向延伸。第2片状物是由在表面片上面接合的薄片形成，该薄片在具有伸缩性的自由缘部折叠，在该折叠的薄片间，第2弹性部件以伸长的状态向第2片状物纵长方向延伸。当使用卫生巾时，第1、第2片状物弹性伸缩的同时与使用者的肌肤相接触。
上述公知的卫生巾中，第1片状物的自由缘部是将重合的表里面薄片以卫生巾呈所要形状裁剪的部分，并为卫生巾外形线的一部分。第1弹性部件沿自由缘部配置在自由缘部的附近，使该自由缘部有伸缩性。当使用卫生巾时，第1片状物的自由缘部，即表里面薄片的切口因没修整而有刺激使用者肌肤的问题。并且，第1弹性部件因有提高该自由缘部刚性的作用，更加重切口的刺激而成为卫生巾穿用感不好的原因。
第2片状物的自由缘由第2弹性部件和被弯折成将其(第2弹性部件)卷进去的片形成，且因第2弹性部件与该片作成整体，往往吃进肌肤地与穿用者肌肤相接触。因而，该第2片状物也成为卫生巾穿用感不好的另一原因。
为此，本发明是以缓和一次性使用的尿布、生理用卫生巾等体液吸收性物品中弹性收缩性片状物对肌肤的刺激为课题的。
为解决上述课题，本发明的对象物是一次性使用的体液吸收性穿用物品，备置本体和多个片状物，该本体具有与肌肤相对的接触面及其里侧的非接触面，并在上述两面间可吸收保持体液，该多个片状物在穿用时一边弹性伸缩一边与穿用者的肌肤接触。
该穿用物品中，本发明的特征如下所述，即，多个上述片状物的任一片具有：有横方向和与其垂直的纵长方向、并从本体向外方延出的薄片；由向上述纵长方向伸长、并被上述薄片覆盖的弹性部件形成、并在上述宽度方向上靠近上述本体的基缘部；从上述本体离开的伸缩性顶缘部。上述薄片，沿在上述顶缘部向上述纵方向延伸的折曲线，将弹性部件做在内侧并折叠，上述弹性部件至少离开上述折曲线1毫米、并位于靠近上述基缘部地与上述薄片的内面接合。
本发明有以下的最佳实施例。
(1)上述弹性部件离开上述折曲线1～20毫米的实施例。
(2)上述片状物由从上述本体向横方向延伸的薄片和上述弹性部件形成，是与上述穿用者的腿围相接触的体液防漏用的片状物的实施例。
(3)上述薄片是坪量为15～50克/米2的无纺布的实施例。
(4)上述穿用物品是一次性使用的尿布、取尿垫片、训练用裤衩、生理用卫生巾、贴身短裤衬垫中的任一物品的实施例。

以下，参照附图详细说明有关本发明的一次性使用的体液吸收性穿用物品。
图1是一次性使用的体液吸收性穿用物品一例的、将取尿垫片1安装在穿着服装一例的尿布罩2上的状态图。尿布罩2是无纺布内面片3和塑料薄膜制的外面片4叠合的，具有前腰围区域6和后腰围区域7和位于两区域6、7间的裆下区域8。在向前后腰围6、7的腰围方向延伸的缘部，腰围弹性部件11、12以伸长的状态安装在内外片3，4间的薄片3、4中的至少一片的内面上。在向裆下区域8前后方向延伸的侧缘部，腿围弹性部件13以伸长的状态与内外片3、4间的这些薄片3，4中的至少一方的内面接合。带状扣件15自后腰围区域7的侧缘部向外方延伸。该带状部件15，是由环部件和钩部件构成的机械式扣件的扣部件组成的，当穿用尿布罩2时，挂止到安装在前腰围区域6外面片4上的由机械式扣件的环部件构成的接合带16。
取尿垫片1是可在尿布罩2内面上装拆的，其具有以裆下区域8为中心相互并排向前后腰围6，7方向(图的纵长方向)延伸的一对侧缘7、和向前后腰围区域6，7的腰围方向(图的横方向)并排延伸的一对端缘18(与图2合并参照)、和为形成垫片1的角部21而在侧缘17的末端和端缘18末端间延伸倾斜的缘19。在侧缘17的内方，可形成与侧缘17并排的在一对端缘18间延伸的防漏片状物20。
图2、3、4、5是在从尿布罩2卸下的取尿垫片1的正面图、背面图、正面图中沿二等分垫片1长度的中心线IV-IV剖切的剖面图及正面图的V-V线剖面图。垫片1具有本体1，该本体1由与穿用者肌肤相接触的透液性表面片22、和位于表面片22里侧的不透液性里面片23及介于两片22、23间的吸液性芯24组成，并按二等分其宽度并向纵方向延伸的中心线C-C对称地形成。
芯24具有：相互并排地向纵长方向延伸的一对侧缘24A，和相互并排地向横方向延伸的一对端缘24B，和从侧缘24A的末端起、芯24的宽度变窄地朝芯24内侧略弯曲的同时倾斜延伸、并与端缘24B末端相连的倾斜缘24C。侧缘24A纵方向的中央部向内侧弯曲，而使芯24的全体呈沙漏钟形。
表面片22具有：沿芯24侧缘24A向纵长方向直线延伸的侧缘22A，和向横方向延伸的端缘22B，和在角部21从侧缘22A的末端略弯曲并倾斜延伸地与端缘22B的末端相连的倾斜缘22C。
里面片23与表面片22同形同大小，并具有：沿芯24侧缘24A直线延伸的侧缘23A，和向横方向延伸的端缘23B，和在角部21从侧缘23A略弯曲并倾斜延伸地与端缘23B末端相连的倾斜缘23C。表里面片22，23分别从芯24侧缘24A的弯曲部位24D、端缘24B、倾斜缘24C向外方延出叠合，并用热熔粘结剂(未图示)相互接合而形成从本体5向横方向延出的侧部片状物10A和向纵长方向延出的端部片状物10B。
防漏片状物20是由无纺布、塑料薄膜等薄片，好的是用不透液性、最好是用通气不透液性的片26形成的，对其长度没有特别限制，在图示例中，沿垫片1的侧缘17向纵长方向延伸并到达端缘18和倾斜缘19。片状物20中使用的薄片26在侧缘17折曲，在垫片1的表面侧，与表面片22用热熔粘结剂27在用斜线所示的角部接合区域51和中央部接合区域52接合(参照图2，4)，而在垫片1的里面侧，与里面片23用热熔粘结剂27在用斜线所示的接合区域28接合(参照图3，4)。薄片26在垫片1的表面侧，沿向纵长方向延伸的折曲线39，向薄片26内侧折曲地重叠，并且片26之间用热熔粘结剂30A接合，形成断面呈环状的防漏片状物20的顶缘部40A。
在薄片26彼此之间，向纵长方向以伸长状态延伸的第1弹性部件34位于防漏片状物20的顶缘部40A，该弹性部件34两端部间，用热熔粘结剂(未图示)与片26连续或间断地接合。该第1弹性部件34还可以在折曲线39的内侧，但希望如图示例地从折曲线39仅离开P尺寸，该尺寸P至少为1毫米，最好在1～20毫米的范围内。
进而，薄片26沿垫片1的外侧缘17折曲重叠，并用热熔粘结剂30B将薄片26彼此间接合，而形成断面呈环状侧部片状物10A的顶缘部40B。
以伸长状态向纵长方向延伸的第2弹性部件36位于侧部片状物10A的薄片26彼此间，并用热熔粘结剂(未图示)连续或间断地与薄片26的内面接合。该第2弹性部件36距离侧缘部17尺寸为R，该离开的尺寸R至少为1毫米，最好在1～20毫米的范围内。第2弹性部件36在位于芯24的弯曲部位24D外方的侧部片状物10A上可形成褶子，并与该弯曲部位24D相对地配置。
如图3所示，在垫片1的里面侧，在芯24的端缘24B各自内侧设置矩形扣件31。扣件31是用于阻止垫片1可能向尿布罩2内面脱落的，对其可使用形成机械式扣件的钩部件和环部件的任一方部件、粘着带等。用热熔接合剂或粘结剂将扣件31如将向垫片1横方向延伸的端部32位于垫片1的角部21那样地安装在里面片23上。
当使用与垫片1成整体的尿布罩2如图1所示向前后方向弯曲时，垫片1也同样弯曲，垫片1的第1、第2弹性部件34、36收缩。当第1弹性部件34收缩时，防漏片状物20产生褶子，同时按图4中双点画线所示以中央接合区域52为基缘部立起，形成朝垫片1开口的袋20A。防漏片状物20的顶缘部40A与穿用者的例如腹股沟部相接触。另外，当第2弹性部件36收缩时，在与基缘部之间产生褶子，该基缘部沿着侧部片状物10A的顶缘部40B和芯24的弯曲部位24D，上述褶子一边收缩一边与垫片1的穿用者的肌肤、例如腿围接触。
该防漏片状物20的顶缘部40A及侧部片状物10A的顶缘部40B具有环状截面，而且由于第1、第2弹性部件34、36从顶缘部40A、40B的折曲线39和实际折曲线的侧缘17离开，当这些片状物20、10A与肌肤相接触时，在各个顶缘部40A、40B，薄片26如图4点画线所示那样膨起或被压扁地变形，因而可防止第1、第2弹性部件34、36向肌肤方向吃入。而且，第1、第2弹性部件34、36由于两端部间与薄片26接合，在顶缘部40A、40B内没有移动，因而可不根据垫片1的穿用状态，而防止第1、第2弹性部件34、36的吃入。
图6是与本发明实施例一例的与图4同样的图。在该取尿垫片1，里面片23比表面片22还长并向侧方延伸出，形成侧部片状物10B，并利用在侧部片状物10B上面接合的薄片26形成防漏片状物20。这样，尿垫片1的侧部片状物10A和防漏片状物20也可用各自的片状材料形成。但是，无论在哪种情况下，片状物10A和20的顶缘部40A、40B的断面都呈环状。
本发明除可对这样形成的取尿垫1、其他的体液吸收装用物品进行实施外，还可以用具有侧部片状物10A和防漏片状物20中任何一方的使用物品进行实施，或对具有穿用物品的多个片状物中的至少一个片状物可适用本发明思想。尤其是，位于穿用物品1表面侧的防漏片状物20往往使用小坪量柔软无纺布，而形成穿用物品外部的侧部片状物10A大多使用刚性较高的片状材料，例如，在形成侧部片状物10A时的里面片23和薄片26，往往使用表面片22很少使用的高刚性的塑料薄膜、坪量15～50克/米2的厚无纺布，相对于含这样材料的侧部片状物10A适用本发明的思想，在提高使用物品的穿用感方面是特别有益的。
本发明中，可以用溶接和其他的结合手段代替用热熔性粘结剂将部件间的接合。有关本发明的一次性使用的体液吸收性穿用物品的例子，除取尿垫片外，有尿布、训练裤衩、生理用卫生巾、贴身短裤衬垫等。这些物品中的片状物的位置和大小并不为实施例所限，可以自由的设计。
有关本发明的一次性使用的体液吸收性穿用物品，将形成弹性伸缩性片状物的薄片，沿按片状物的顶缘部的断面呈环状沿成为片状物的顶缘线折曲接合，使给该片状物付与伸缩性的弹性部件从相对于该薄片折曲时的线到靠近片状物的基缘部至少离开1毫米，当片状物的顶缘部与肌肤相接触时，薄片因在其顶缘部分别的变形，起缓冲效果，因而可解除因弹性部件吃进肌肤的作用而恶化穿用物品穿用感的问题。
